This popular kit is designed to bolt on with no modifications and virtually eliminate belt slippage at the supercharger pulley. The included aluminum mounting bracket is precision-machined and mounts to existing bolt locations, and the unique design provides unmatched durability and strength.

This kit includes a black hardcoat-anodized 90mm idler pulley, which is the smaller size that serves to maximize belt wrap in applications using stock size supercharger pulleys.

The kit includes a billet bearing cover for the pulley (not shown), and illustrated installation instructions are provided.

Note: This kit is available with a larger 100mm idler pulley for applications using an overdrive (smaller) supercharger pulley under Metco Motorsports PN MCI-100, also listed in this section.
